Biological safety cabinet that can provide digital experiment environment and its control method

Abstract

The invention provides a biological safety cabinet capable of providing a digitalized experiment environment and a control method of the biological safety cabinet. The biological safety cabinet comprises a biological safety cabinet body and a biological safety cabinet outer wall, and further comprises a temperature and humidity sensor, a control unit and a temperature and humidity regulator which are arranged in the cabinet body, a display screen arranged on the biological safety cabinet outer wall, video equipment arranged at the outer top of the cabinet body, and a computer arranged outside the cabinet body, wherein the temperature and humidity sensor is connected with the control unit; the control unit is connected with the temperature and humidity regulator, the display screen and the computer; the control unit is used for converting a temperature and humidity signal measured by the sensor into a digital signal and outputting the digital signal to the display screen and the computer; temperature and humidity data can be compared, regulated and controlled and stored by the computer; and the video equipment is connected with the computer. The biological safety cabinet capable of providing the digitalized experiment environment can be used for easily measuring and automatically controlling a biological experiment environment, and recording related experiment data.

Description

technical field [0001] The invention relates to a biological experiment equipment and a control method thereof, in particular to a biological safety cabinet capable of providing a digital experiment environment and a control method thereof. Background technique [0002] The requirements for the use of biological safety cabinets are: when doing related experiments, a negative pressure is formed inside the biological safety cabinet, and the airflow enters the cabinet from the front windshield, passes through the air duct, and enters the fan suction port, and then the fan pushes the airflow to distribute to the upper, The airflow passing through the upper filter is directly discharged indoors or outdoors through the lower filter, and the airflow passing through the lower filter enters the operating area, merges with the airflow from the suction port and enters the next repeated cycle process. Different types of biological experiments have different purposes, and the experimenta...

Problems solved by technology

However, ordinary biological safety cabinets are still unable to meet the requirements of medical workers to accurately record a series of work data, so that the accuracy of biological experiments cannot be further amplified.
